It is increasingly difficult to find sand mining sites on dry land. Therefore, sea sand is an interesting alternative, as much in Belgium as in our neighbouring countries. In Belgium, the percentage of sea sand production in relation to total sea sand production has continued to rise since the 1970s. Sea sand is used in the construction sector as well as to protect the Belgian coast.Top 10 mitigating measures for offshore sand mining,sand mining (outside the navigational channels) is allowed up to a maximum depth of 2 m. However, due to the land reclamation for the Maasvlakte 2 at Rotterdam (about 350 million m3 are needed), therefore pits will be created at 5 to 20 meters depth.OFFSHORE SAND AND GRAVEL MINING - ResearchGate,OFFSHORE SAND AND GRAVEL MINING E.
